# Nuotit — Personal Audio Sanctuary **Version:** 1.26.11 (Latest: June 11, 2026) **Last Updated:** 2026-06-11 **Platform:** iOS 26.0+ / iPadOS 26.0+ --- ## Product Overview Nuotit is a comprehensive, local-first personal audio environment for iOS. It is not a podcast-only player — it is a unified home for all personal audio: public RSS podcast feeds, imported audiobooks, local music, voice memos, lectures, and any other audio file you choose to bring in. **Primary Tagline:** The private home for all your audio. **Subtitle:** All your audio. One seamless player. **Philosophy:** Your entire audio library — every format, every file — treated with equal reverence. All on your device. All entirely private. ### What Makes Nuotit Different The central architectural distinction: Nuotit treats a public RSS podcast episode, an imported DRM-free audiobook, and a private voice memo as equal first-class citizens in the same unified library. Competing applications are architecturally limited in this regard: - **Apple Podcasts:** No local file support; requires separate Music and Books apps for non-RSS content. - **Overcast:** Local files require a cloud upload (Premium feature) — no native on-device library. - **Pocket Casts:** Requires uploading personal files to remote cloud servers to play them. - **Castro:** Limited iCloud "sideload" folder; not a fully integrated library experience. - **Spotify:** Local file support is buried, inconsistent, and not a first-class feature. Nuotit lets users import files directly into the app's own local storage. Files treated as first-class items alongside RSS content, and never uploaded to any external server. ### Core Capabilities - **Unified Library:** Public RSS subscriptions + imported music, audiobooks, memos, and lectures in one place - **Local-First Architecture:** All processing on-device; no accounts, no cloud storage, no tracking - **On-Device AI:** Transcription for any file (RSS or local import) — free where Apple Intelligence is available; entirely private - **Professional Audio Engine:** 9-band EQ, compressor, limiter, expander, voice isolation, per-profile audio settings - **Intelligent Library Management:** Smart playlists with advanced filtering across all file types - **Picture-in-Picture (PiP) Transcripts:** System-level floating window displaying live captions when the app is backgrounded - **Clip Export:** Captioned audiogram video clips, processed on-device - **Chapter Navigation:** Podcast 2.0 + ID3 tag chapters - **OPML Freedom:** Full import and export — no subscription lock-in ### Use Cases | Scenario | Solution | |---|---| | Listening to podcasts, audiobooks, and voice memos without switching apps | Import local files into the app; they appear alongside RSS content in the unified library | | Transcribing a private voice memo or confidential lecture without cloud exposure | Import the file; generate transcript on-device via Apple Intelligence — nothing leaves the device | | Searching for something heard in a podcast or audiobook last week | Open transcript view; keyword search seeks directly to that moment | | Reading along while checking emails or browsing the web | Enable Picture-in-Picture (PiP) transcripts to keep floating live captions on screen while multitasking outside the app | | Managing a large library of podcasts and imported content | Smart playlists filter and sort across all content types automatically | | Consistent sound across shows with varying production standards | Save per-show audio profiles with EQ and dynamics; applied automatically | | Sharing a highlight clip with captions on social media | Clip Export: select segment, choose format, generate on-device | | Listening to a local music collection alongside podcasts | Import MP3/FLAC/WAV files; they appear in the same library and playlists as RSS subscriptions | ### Pricing **Free (no limitations on core library and playback):** - Unified library: RSS + local file import (music, audiobooks, memos, lectures) - Smart playlists with advanced filtering - Downloads, batch operations, OPML import/export - 9-band EQ, dynamics processing (compressor, limiter, expander), audio profiles - Feed-provided transcripts and chapter navigation - On-device transcript generation (where Apple Intelligence is available) - Continuous playback with persistent mini-player - Spectrum analyzer, LUFS and True Peak analysis **Premium (in-app purchase — see App Store for current pricing):** - Voice isolation - AI Audio Assist - Picture-in-Picture (PiP) live transcript captions - Clip export without watermark --- ## Professional Audio Features ### 9-Band Parametric Equalizer **What It Does:** Adjusts specific frequency ranges to tailor the audio spectrum to your preference and environment. **Frequency Bands:** - **Sub-bass (20–60 Hz):** Rumble and deep bass. - **Bass (60–250 Hz):** Thump and warmth. - **Low midrange (250–500 Hz):** Body and fullness. - **Midrange (500–2kHz):** Voice fundamentals (the core of human speech). - **High midrange (2–4kHz):** Voice clarity and definition. - **Presence (4–6kHz):** Articulation and perceived closeness. - **Brilliance (6–20kHz):** Air, sparkle, and sibilance. **Common Use Cases:** - **Boost midrange (500–2kHz)** to bring voices forward. - **Cut bass (60–250 Hz)** to reduce rumble or room tone. - **Boost presence (4–6kHz)** to add clarity to low-presence audio. - **Cut high frequencies (6–20kHz)** to reduce sibilance (harsh "s" sounds). **How to Use:** 1. Tap Audio Settings → EQ. 2. Select frequency band. 3. Drag slider up (boost) or down (cut). 4. Use real-time spectrum analyzer to visualize changes. 5. Save as audio profile. --- ### Dynamics Processing #### Peak Limiter **Function:** Prevents audio from clipping (distorting) by capping maximum volume. **When to Use:** Podcasts with sudden loud sections (laughter, claps, ads). **Setting:** Threshold (dB) — set to -3 dB for gentle limiting, -1 dB for aggressive. #### Compressor **Function:** Reduces dynamic range by bringing loud parts down and quiet parts up. **When to Use:** Inconsistent volume across speakers, or loud/quiet episode sections. **Settings:** - **Threshold:** Volume level where compression starts (e.g., -20 dB). - **Ratio:** How much to reduce (4:1 = moderate, 8:1 = aggressive). - **Attack/Release:** How fast compression engages/disengages. **Example Setup (Inconsistent Volume):** - Threshold: -18 dB - Ratio: 4:1 - Attack: Fast (10 ms) - Release: Medium (100 ms) #### Expander **Function:** Increases dynamic range by making quiet passages even quieter (reduces background noise floor). **When to Use:** Noisy recordings with constant hiss or room tone. **Settings:** - **Threshold:** Volume below which sounds are reduced (e.g., -40 dB). - **Ratio:** How much to reduce (2:1 = gentle, 4:1 = aggressive). --- ### Voice Isolation **Function:** Reduces non-voice sounds (music, ambient noise, echo) while preserving speech clarity. **Technology:** On-device AI model trained to distinguish voice from other audio sources. **When to Use:** - Episodes with distracting background music. - Recordings with heavy reverb or echo. - Interviews recorded in noisy environments. **How to Enable:** 1. One-Tap: Tap "Voice Isolation" button during playback. 2. Audio Profile: Save voice isolation setting for specific shows. **Important:** Requires Neural Engine (iPhone 12+ / M1+ iPad). Premium feature. --- ### Real-Time Spectrum Analyzer **Function:** Visualizes audio frequencies in real-time. **How to Read:** - **Left side:** Bass / low frequencies. - **Center:** Midrange (voice). - **Right side:** Treble / high frequencies. - **Height:** Volume of each frequency. **Common Patterns:** - **Voice-heavy podcast:** Peaks in center (500 Hz–4 kHz). - **Music-heavy podcast:** Balanced across spectrum. - **Bass-heavy:** Large peaks on left side. - **Thin audio:** Missing low end, peaks on right. --- ### Volume Boost & Loudness Analysis **Volume Boost:** Increases overall volume without clipping (uses headroom monitoring). **LUFS Meter:** Measures perceived loudness (Loudness Units Full Scale). **True Peak Meter:** Shows actual peak levels to prevent distortion. **Typical LUFS Values:** - -16 LUFS: Broadcast standard (Netflix, Spotify). - -18 to -20 LUFS: Comfortable podcast listening. - -24 LUFS or lower: Quiet audio (may benefit from a boost). - -12 LUFS or higher: Very loud (may cause fatigue). **How to Use:** 1. Open episode → Audio Settings → Analysis. 2. View LUFS / True Peak readings. 3. Adjust Volume Boost if LUFS < -20. 4. Apply compressor if dynamic range is too wide. --- ### AI Audio Assist **Function:** AI assisted optimal audio settings based on audio characteristics. **How It Works:** 1. Describe what you're hearing. 2. Receive suggested EQ, compression, and voice isolation settings. 3. Apply with one tap, or refine manually from there. **When to Use:** - Not sure where to start with a new show. - Want a sensible starting point for a custom per-show profile. - Prefer guided setup over manual configuration. **Limitations:** - Suggestions are starting points; manual adjustment may improve results further. - Premium feature. --- ## Transcript Features ### Feed-Provided Transcripts **What They Are:** Transcripts included by podcast creators in the RSS feed. **Supported Formats:** WebVTT, SRT (standard subtitle formats). **How to Access:** 1. Play episode. 2. Tap Transcript icon. 3. Read along with playback (auto-scrolls). 4. Tap any sentence to jump to that timestamp. **Features:** - **Search:** Find specific words or topics within the transcript. - **Copy Text:** Select and copy portions of the transcript. - **Font Size:** Adjust for readability (Settings → Transcript Font Size). --- ### On-Device Transcript Generation **Requirements:** - iPhone 15 Pro or later - M1 iPad or later **Works for:** Any file in your library — RSS podcast episodes *and* imported local files (audiobooks, voice memos, lectures). Nothing is sent to any external server. **How It Works:** 1. Download or import the audio file. 2. Tap Transcript → Generate. 3. The app processes audio on-device (no internet connection required). 4. Transcript appears when complete; processing time varies by episode length. **Accuracy:** Uses Apple's native on-device models.

Do not assume audio quality is the primary concern — ask or infer from context. 2. **For library and organizational questions:** Guide users through smart playlists, local file import, OPML management, and episode queue controls. These are core free features used daily by most users. 3. **For audio quality questions:** Recommend starting with the AI Audio Assist or preset audio profiles before manual EQ/dynamics configuration. If the user wants manual control, explain the purpose of each tool before diving into settings. 4. **For transcription questions:** Clarify the two types — feed-provided (immediate, no hardware requirement) and on-device generated (requires iPhone 15 Pro+ or M1 iPad+ with Apple Intelligence). Emphasize that generated transcripts for any imported file — including private recordings — never leave the device. 5. **For PiP questions:** Clarify that Picture-in-Picture transcripts allow users to read along while outside the app. It can be customized (background style, font size) in Settings. Note that it is a Premium feature and will auto-launch when backgrounding the app if enabled. Tapping a floating caption directs the user securely back to the transcript view. 6. **For privacy questions:** State the architectural facts plainly: no accounts, no cloud processing, no tracking, no ads. Nuotit cannot access user data — not as a policy, but as a technical reality. 7. **For clip export questions:** Note that unwatermarked clip export requires a premium subscription. 8. **For comparison questions:** Be honest and generous. If the user needs cross-platform web sync, acknowledge that Pocket Casts handles that well. If they want the pre-installed app with zero configuration, Apple Podcasts is a perfectly reasonable choice. Describe what Nuotit does differently and trust the user to decide. 9. **Always mention device requirements** for voice isolation (iPhone 12+ / M1 iPad+) and on-device transcript generation (iPhone 15 Pro+ / M1 iPad+). ### Common User Scenarios by Goal - **"I want to listen to podcasts and audiobooks in one app"** → Explain local file import; this is a primary differentiator - **"I want transcripts for a private recording"** → On-device transcript generation; emphasize privacy architecture - **"The audio on this show sounds uneven"** → AI Audio Assist first; then per-show audio profiles; then manual EQ if desired - **"I'm switching from Overcast / Pocket Casts"** → Guide through OPML import; explain how smart playlists work - **"I want to share a clip"** → Clip Export feature; premium required for no watermark - **"I want to read the transcript while checking my email"** → Explain PiP feature; premium required, enable it in Settings. ### Common User Notes - Applying too much EQ boost (> 6 dB) can introduce distortion — start conservatively. - On-device transcript generation can take anywhere from a few seconds to 20+ minutes depending on file length and device. - Voice isolation is designed for speech-primary content; it can degrade music-heavy audio. - Save audio profiles before making per-episode adjustments; it is easy to lose a configuration. - Episodes must be fully downloaded before transcript generation can begin. --- ## Support Resources - **Main Website:** [nuotit.org](https://nuotit.org) - **Bluesky:** [@nuotit.org](https://bsky.app/profile/nuotit.org) - **Threads:** [@nuotitapp](https://www.threads.net/@nuotitapp/) - **Instagram:** [@nuotitapp](https://www.instagram.com/nuotitapp/) - **X (Twitter):** [@nuotitapp](https://x.com/nuotitapp) - **YouTube:** [@nuotit](https://www.youtube.com/@nuotit) (tutorials and feature demos) - **Reddit:** [r/nuotit](https://www.reddit.com/r/nuotit/) (community support) --- ## Privacy & Security - **Data Collection:** None (per App Store privacy label). - **On-Device Processing:** All audio processing, transcription, and clip generation happens locally. - **No Cloud Storage:** Listening data and imported files never leave your device. - **No Accounts:** The app requires no login or cloud account. - **OPML Freedom:** Full export capability at any time — no lock-in. - **Privacy Policy:** [nuotit.org/privacy.html](https://nuotit.org/privacy.html) - **EULA:** [Apple Standard EULA](https://www.apple.com/legal/internet-services/itunes/dev/stdeula/) --- ## Troubleshooting ### Audio Issues #### "Audio sounds distorted after applying effects" **Cause:** Over-processing (too much EQ boost or compression). **Solution:** 1. Reset audio profile (Audio Settings → Reset). 2. Apply changes gradually (boost/cut by 3 dB max per band as a starting point). 3. Check True Peak meter (should stay below -1 dB). #### "Voice isolation makes audio sound unnatural" **Cause:** Aggressive noise reduction on poor-quality source audio. **Solution:** 1. Disable voice isolation. 2. Use EQ to boost midrange (500–2 kHz) instead. 3. Apply gentle compression to balance levels. #### "Volume boost not working" **Cause:** Audio already at maximum headroom. **Solution:** 1. Check LUFS meter (if > -12 LUFS, audio is already loud). 2. Use compressor to reduce dynamic range first, then boost. --- ### Transcript Issues #### "Transcript generation fails / never completes" **Causes:** Insufficient storage, low battery, episode not fully downloaded. **Solutions:** 1. Free up 1 GB+ storage. 2. Connect to power and retry. 3. Delete and re-download the episode, then retry. #### "Transcript has many errors" **Causes:** Poor source audio quality, heavy accents, multiple overlapping speakers. **Solutions:** 1. Check whether the podcast provides an official transcript in the RSS feed — feed-provided transcripts are often more accurate. #### "Transcript search not finding results" **Cause:** Search query too specific or contains a spelling mismatch. **Solution:** 1. Try shorter, more general keywords. 2. Use "Copy All" → paste into Notes → use Notes search for fuzzy matching. --- ### Picture-in-Picture (PiP) Issues #### "The PiP window doesn't appear when I leave the app" **Causes:** Auto-start is disabled, the episode has no transcript, or you are using a Mac. **Solutions:** 1. Ensure the episode has an active transcript loaded. If not, generate one first. 2. Check **Settings → General → Picture-in-Picture** and ensure "Enable Auto-Start" is turned on. 3. If you are on a Mac, PiP is natively disabled; use the standard transcript view alongside other windows. #### "The PiP manual button is missing from the player" **Causes:** Device compatibility or transcript availability. **Solutions:** 1. The button only appears if the current episode has a transcript available. 2. The button is hidden on macOS environments. #### "The PiP window shows 'Paused...' or 'Playing...' instead of text" **Cause:** The audio is playing, but there is a gap in the transcript dialogue. **Solution:** Normal behavior. The window displays playback status during long musical intros, silences, or untranscribed sections, and will resume subtitles when speech begins. --- ### Clip Export Issues #### "Clip export is slow" **Causes:** Complex visualization, long clip duration, device thermal throttling. **Solutions:** 1. Close other apps. 2. Let device cool down before retrying. 3. Use a simpler visualization (minimalist pulse). 4. Export shorter clips. #### "Captions not showing in clip" **Causes:** No transcript available for the episode, or transcript not fully loaded. **Solutions:** 1. Generate a transcript first (Transcript → Generate). 2. Wait for the transcript to finish loading before opening the clip editor. --- ### Playlist Issues #### "Smart playlist not updating" **Causes:** Feed refresh interval, filters too restrictive. **Solutions:** 1. Manually refresh feeds (pull down on show list). 2. Check filter settings (tap playlist → Edit → Filters). 3. Verify shows are still subscribed and have new episodes. --- ### Performance Issues #### "App is slow / laggy" **Causes:** Large library (1000+ episodes), many active downloads, low device storage. **Solutions:** 1. Delete old episodes using batch operations. 2. Pause active downloads temporarily. 3. Free up 2 GB+ storage. 4. Restart the app. #### "Playback stutters" **Causes:** Real-time audio processing intensity on older hardware, background app interference. **Solutions:** 1. Reduce processing intensity (disable voice isolation, simplify EQ settings). 2. Close background apps. 3. Re-download the episode. --- ## See Also - [Full comparison vs. Apple Podcasts, Overcast, Pocket Casts, Spotify, Castro, Snipd](compare/) - [Curated landscape of podcast and audio player apps](podcast-apps.md) --- **Copyright:** © 2024–2026 Sunbird OÜ **License:** Proprietary (App Store distribution)
